The only effective way I can think of (keeping in mind I am not one of the world's great thinkers) would be to turn the barrel down over the ports then fit a sleeve over that portion of the barrel. It could be soldered or glued or even threaded on. The sleeve would have to be drilled and tapped for the front sight base of course (I think those used a Williams sight). Properly done, the sleeve would be virtually undetectable. This would even better than a vasectomy reversal because it would be 100% certain! Regards, Bill.

I've got a magnaported Whitworth 375 that came to me ported. We used it in Namibia with great results and I love the rifle. I'd shot it from the bench with muffs and plugs, no problem. In the field (where I never feel recoil anyway), it sure rung our ears, especially as I was winging follow up shots and my son's wounded gemsbok. I know I can cut off the barrel and re-fix the sights. This would take a 24 inch barrel to 22 inches, which itself would increase muzzle blast a bit. I also thought about finding a banded front sight, and have the band cover the ports. HOwever, the ports would need 1.3 inches of coverage and NEGC banded front sights just cover 1 inch and change. Any other way to deal with a magnaport? Thanks, Bob
